I messed up...
I just bought a 128GB SD card and to get better I/O from it I set the policies to "Better Performance" which of course forces me to Safely remove hardware before pulling the card from my laptop. Which is how I always work already.
BUT... this time I was distracted and didn't wait for the confirmation message before removing the card. Now none of my machines can access the card. An SD card is seen but nothing else, even the drivers don't load.
Anyone out there have any suggestions?
